'MACHINE FOR MAKING BOTTLES, 800.

SPECIFICATION forming part of Letters Application filed December 31, 1

To all whom it may concern:

Be it known that I, CLAUDE BoUoHER, a citizen of the Republic of France,residing at Cognac, in the Republic of France, have invented certain newand useful Improvements in or Relating to Machines for Making Bottlesand other Articles of Blown Glass, of which the following is aspecification.

The present invention relates to a machine for making bottles and otherarticles of blown glass, and comprisestwo measuringmolds, two molds forforming the neck, and two mouth-forming plungers which are arranged towork alternatively, so that they cannot be overheated to such a degreethat the glass might adhere to the walls of the molds.

My invention in its preferred embodiment is illustrated in theaccompanying drawings, wherein Figure 1 is a horizontal section taken online m just above the base of the machine. Fig. 2 is a vertical viewtaken on line A B, Fig. 1. Fig. 3 is an enlarged section through theneck-molds, their supporting-arms, and associated parts. Fig. 4 is avertical sectional view taken on line C 'D, Fig. 1, looking toward theleft, Fig. 2. Fig. 5 is a similar View taken on line E F, Fig. 1,looking to the right, Fig. 2, both of the measuring and one of the neckmolds being shown open.

Referring to the drawings, 1 is the baseplate of the machine, having twostandards 2 and 58 thereon. At the top of standard 2 and arranged inbearings 31 31, provided with oil-cups 35, is a rotatable horizontalhollow shaft 3, having a fixed extension'50, said shaft 3 being providedwith hand-wheel 30, keyed at one end, and a face-plate 4, carryingmeasuring-molds a a at each extremity,at the other end, said face-platebeing provided at its center with a boss 5, having two bent arms 6 6,carrying the neck-molds 20 and 20. The measuring-molds a Cb, each formedin two parts, are fixed to the face-plate 4 by means of adjustablescrew-bolts 11 passing through slots 16 (see Fig. 5) in said face-plateand are held in position by lock-nut 17. The slots 16 allow of verticaladjustment of the measuring-molds. The two parts of the said molds arebrought togetherfor closing the molds and are moved apart when openingthe molds by means of a toothed wheel 8, engaging two Patent No.711,818, dated October 21, 1902.

901- Serial No. 87,910. (No model.)

pinions 9 9, mounted on a shaft 10, which passes through the arms of themold parts and the inner ends of bolts 11 11. The pinions 9 are fixed tothe arms of the mold parts and are operatively connected to theintermediate wheel 8, which is loosely mounted on a short axle d. Thisarrangement enables the operator to close the mold by moving one moldpart by means of a handle 12 attached thereto, movement beingtransmitted to the other part through the gearing. The two halvesconstituting the mold are held in closed position by means of a hook orcatch 13 in one part engaging a hole 14in the other. A bot tom part 15(see Fig. 5) is adapted to close the open end of the measuring-moldswhen they are in their closed position by turning handles 14 thereon andinserting them in the slot (see Fig. 5) of the mold halves.

In Fig. 2 the measuring-mold a is shown in its open position with itsinlet-opening turned downward, while the measuring-mold Cb appears inthe position it occupies after a quantity of glass sufficient for themanufacture of the article to be obtained has been poured into it. It iswhile the mold is in this position that the molten glass therein iscompressed by means of a steam or compressed air-j et in order to obtaina homogeneous mass and toenable delicate ornaments and inscriptions tobe produced by causing the glass to adapt itself more perfectly to theshape of the mold. The steam or compressed air by opening valve 3through the operation of treadle q passes from pipe t, communicatingwith any suitable source, to pipe 0, thence through movable bracket g,carried by standard 58, and finally from funnel h to the measuring-mold.The measuring-molds are sufficiently large to enable the glass to bereadily introduced into them and terminate at their opposite ends in aneck or collar, which when the mold is in its closed position fitsagainst its corresponding neck-mold 2O 20', one carried on each of thebent arms 6 6 of boss 5. In Fig. 2 measuring-mold a. is shown inengagement with neck-mold 20. Each neckmold, like its correspondingmeasuring-mold, is formed of two parts hinged together and consists of acasing 21, divided longitudinally into two parts, and of a mold properarranged inside, which has the exact form to be given the neck of thebottle. The two parts of each mold are adapted to be fastened togetherwhen the mold is in its closed position'by engaging book 25 on one partwith hole 26 on the other. In Fig. 5 the parts are shown in their openposition. The neck-molds 2O 20' and the measuring-molds a a are movedalternately into the position for receiving the molten glass, in whichposition the opening of the measuring-mold is at the top. This movementis effected by means of a handwheel 30, keyed to hollow shaft 3,actuating the face-plate 4, and boss 5, forming part thereof. To securethe measuring-molds in their respective vertical positions, a recess 18is provided at each extremity of the faceplate 4, and after the latterhas been rotated through an angle of one hundred and eighty degrees saidrecess 18 bears against a roller 33 of a locking-bar 32, which ispressed upward by a spiral spring 34;, as clearly shown in Fig. 5. Whenthe measuring-mold is in its lower position, compressed air for blowingthe bottle passes from the pipes 15 and it through stuffing-box 1; intothe hollow rotatable shaft 3.

through a fixed extension 50, Fig. 3, of said shaft, and thence throughthe bent arm 6 in the direction of the arrows to the neck-mold in thelower position. Extension-shaft 50 is fixed and is secured in standard58 by nuts 23 23, and near its hollow end is formed in the shape of acrank-shaft 22, on which is a bushing 29. A collar 28, embracing saidbushing, supports two mandrels 27 27, terminating in screwed rods, whichare recessed in the collar at diametrically opposite points. Saidmandrels are moved alternately into the neckmolds 2O 20 immediatelybefore the introduc tion of the glass into the measuring-mold by thelongitudinal movement transmitted to sleeve 28 by the movement ofhand-wheel 30. The mandrel 27is inserted into the neck-mold 20 or 20when the mold takes up its upper position below the measuring-mold, asmay be readily seen from Fig. 5, in which the neckmold is shown open.Then one of the mandrels is inserted into the neck-mold 20 in the upperposition, the other is withdrawn from the neck-mold 20 in the lowerposition to allow compressed air to enter the cavity formed by themandrel. The mandrels 27 have a diameter corresponding to the upper partof the neck of the bottle and are made to fit exactly with theinwardly-projecting flange 21 of the neck-molds, though not quitefilling the guidesleeve 24. It is obvious that by this arrangement thecompressed air is enabled to enter the neck-mold through guide-sleeve 24and after the completion of the perforation of the neck'part of thebottle by the mandrel to enter the bottle itself when the mandrel hasbeen removed from contact with flange 21, thus forcin g the glassagainst the walls of the mold. At the same time the compressed air isprevented from entering the upper neck-mold, as the correspondingmandrel is in contact with flange 21 of said neck-mold. Moreover, as theextension-shaft 50 is provided with only one opening on its lower side(see Fig. 3) the compressed air can pass only to the lower arm 6.

A finishing-mold c is supported by adjustable threaded bolts 39, whichpass through standard 58, to which they are fixed by nuts 46. The axle40, which passes through the heads of the bolt, receives the hinge-arms36 of the finishing-mold parts A slot j, provided in the standard 58,enables the finishing-mold to be adjusted vertically, according to itslength and special form, so that the neck always joins exactly theneck-mold in its lower position. For closing and opening thefinishing-mold the two parts may be brought together or moved apart bymeans of a-handwheel 57, operating a shaft 59, to the end of which awheel 37 is keyed to transmit the movement to pinions 38, arranged 011the hinge-arms 36 of the finishing-mold. The shaft 59, carrying thewheel 57, turns freely in a sleeve 70, formed with a stud passingthrough the central slot of the standard. This sleeve 76 is held inposition with regard to the standard by bolts 60, which are arranged topass through a flange provided on the sleeve and through side slots.

The manufacture of bottles and other similar articles by means of themachine in question will now be described. One of the measuring-molds isplaced by means of the handwheel in its upper position, as shown in Fig.2, whereby the mandrel is automatically inserted through the crank-shaftinto the neckmold situated underneath this measuringmold. After this hasbeen done the operator introduces a quantity of glass necessary forproducing the bottle or other article desired into the mold, whereuponthe operator moves the funnel 7?, by means ofthe handle 1', so as toclose the opening of the measuring-mold. By actuating the treadle q andopening thereby the valve 8 compressed air is admitted above the glass,which by this means becomes homogeneous and is applied in an efficientmanner to the neckmold situated underneath the measuring-mold, so as toenable the collar and other ornaments to be formed in a perfect manner.This operation of compression ought to be made rapidly, so as to enablethe glass to remain plastic. The operator now removes the funnel h,which then moves to the position shown in Fig. 4,'and places the bottompart 15 on the inlet-opening of the measuring-mold a. The mold is nowbrought into its lower position by turning the handwheel 30. During thishalf-revolution, by which the position of the measuring-mold is changed,the crank-shaft 22 causes one of the mandrels to enter the neck-mold onreaching its upper position, while at the same time the mandrel of theneck-mold which is moved downwardly is withdrawn, so as to allowcompressed air to pass through the sleeve 24. The mandrel having thusbeen withdrawn from the cavity made in the glass at the neck of theorifice, the second treadle p is now op- ITO erated to open the valve owhereby compresed air is admitted from the supply-conduit t,communicating with a compressed-air reservoir or any other convenientsource. After the glass has been sufficiently solidified by the actionof the compressed air and by contact with the walls and bottom of themold the operator removes the bottom part 15 and opens the mold bydisengaging the hook 13 on one half from the hole 14 on the other. Therough bottle is now suspended by its neck from the neck-mold 20. Theoperator then places the holder b against the bottom of the rough bottle60 and by admitting a small quantity of air into the interior of thebottle causes its lower end to assume the exact form of the holder, bywhich means the desired homogeneity of the material of the bottle isobtained. After the rough bottle 60 has assumed its proper length, so asto bear upon the bottom part 47 of the finishing-mold, the operatorcloses the finishing-mold by turning the hand-wheel 57, whereby the twomoldvalves fit closely around the bottom part 47, which has been raisedthrough the medium of lever 53, and inclose the rough bottle, which nowreceives its final form by the introduction of compressed air, which isadmitted by actu ating the treadle p and opening the valve 1- of thecompressed-air-supply tube 11,. After the bottle has received its finalform in consequence of the glass having been forced against the wallsand the bottom of the finishingmold by the action of the compressed airthe mold is opened by disengaging the retaining means 42 43, so as tooccupy the position represented in Fig. 4. Then the neckn1old is openedby removing the hook 25 from its hole 26, with which it was engaged. Inthe case of bottles having a fiat or concave bottom the manufacture isfinished; but if the bottle is to be provided with a recess in thebottom a suitable auxiliary device for deepening the recess to the depthdesired may be used.

I claim 1.
